DESCRIPTION

Heldite jointing compound is a high-performance sealant for preventing leakage of Petrol, Diesel Fuel, Hydraulic Fluids, Oils, Paraffin, LPG’s, Water, Steam and Gases in all branches of Automotive, Auto mechanical, Electrical and General Engineering, Plumbing, Heating and Pipeline Services. Heldite is a thick liquid compound that can be applied to any joint either with or without a gasket.

It will effectively seal bolted, flanged or screwed joints and as it is in a liquid form it is economical to use and does not tend to squeeze out into the interior of a joint and cause damage. Heldite is non-abrasive and will not damage highly machined joint faces; the combination of thermal, plastic and adhesive factors in this jointing compound is unique in the sealant formulation. The plasticity combats the effects of temperature and pressure changes, shifting levels and stresses associated with the assembly of dissimilar metals such as aluminium housings bolted to cast blocks. The adhesive factor not only assists gasket location but has been shown to be an effective locking sealant for imparting additional security to splines, studs and press fit bearings.

FEATURES AND BENEFITS

• Prevent leakage of oils, hydraulic fluids, water, steam, gases, coolants and fuels
• Multi-purpose product - Adhesive and sealant
• Anti-corrosive and inert - Inhibits corrosion and can be used to seal electrical components to resist moisture ingress
• Water resistant
• Accurate application - Applied by brush
• Flexibility - Combats vibration and stress imposed by temperature changes in dissimilar metals and materials
• Adhesion - Aids gasket location and security of studs, splines and press fit bearings
• Sealant - Resistant to most types of fluid used in automotive sector (not compatible with Ethanol)

APPLICATION INFORMATION

Apply a coat of Heldite to each face and allow it to remain a few moments until the compound becomes tacky. Close the joint. For screwed joints, apply one coat to each mating thread and screw up immediately. For joints made with washers of cork or absorbent material, apply one coat to each side of the washer or gasket and allow this to soak in. A second coat should be applied to the joint faces, allow it to become tacky and then close the joint. Heldite is a solvent based product and needs to dry out in order to work effectively; this can take between 20mins and 8hrs. If the joint is to be put under pressure immediately or if the quality of the screw threads are in doubt and in the case of parallel threads - the use of a packing material (ie hemp or ptfe tape) is recommended after coating the threads with Heldite. This will support the Heldite jointing as it sets - a belt and braces approach. It is advisable to allow Heldite to set completely before putting the joint under full pressure.
